The growing clergy letter project is, I believe, a fine example of compartmentalization. "We ask that science remain science and that religion remain religion, two very different, but complementary, forms of truth."

Started by a biologist who was fed up with creationism, it has become a safe haven for Christians from critical thought. I agree with fundamentalist Jefferson Reed that the signers of the petition are Apostates who deviate from the plain reading of the Bible. I believe it is nothing more than a cursory way of eliminating cognitive dissonance. One can now feel much more comfortable accepting evolution while maintaining faith simply because thousands of others have publicly done so - never mind that research and critical thought would be a much better way to evaluate whether religion and science are compatible. No one will ever force the different compartments to a debate.
